Fermentation

2. Anaerobic Respiration
Anaerobic Respiration Requires NO Oxygen!
Organisms that use only anaerobic respiration include:
Prokaryotic: Bacteria, Yeast
Eukaryotic: Some Fungi, Many aquatic invertebrates

3. Anaerobic Respiration
The anaerobic pathway that follows glycolysis is called FERMENTATION
It occurs in the CYTOPLASM and regenerates the carrier molecules, which allow glycolysis to loop.

4. Two main types of fermentation
Lactic acid fermentation
Alcohol fermentation

5. Lactic acid fermentation
The PYRUVATE made during glycolysis is converted to lactic acid.
Although it produces no ATP, this process replenishes the carrier molecules required to run glycolysis (which does)

6. Alcohol fermentation
The PYRUAVTE made during glycolysis is converted to ethyl alcohol by releasing a molecule of CARBON DIOXIDE.
Although it produces no ATP, this process replenishes the carrier molecules required to run glycolysis (which does)
